You are caring for a 52-year-old woman whose sisters and mother died of breast cancer. The patient states, "My doctor wants me to take tamoxifen to help prevent breast cancer. What do you think?" What would be your best response?
A) "We call this drug a chemotherapy agent."
B) "Tamoxifen prevents osteoporosis."
C) "I would recommend raloxifene."
D) "Tamoxifen reduces the incidence by 49%."
Ans: D
Feedback: Tamoxifen is referred to as a chemopreventive agent, not a chemotherapeutic agent. It does prevent osteoporosis, but this response does not address breast cancer prevention. Raloxifene (Evista) is another drug that shows promise as a chemopreventive agent. Tamoxifen reduces breast cancer incidence by 49%.
